This eliminates the unnecessary extra weight required in conventional systems of carrying both a backpack and a groundcover. Furthermore, the convertible ground cover and backpack may be easily cleaned during and after any of the outdoor activities disclosed herein.

FIGS. 1-3 depict various non-limiting embodiments of a convertible ground cover and backpack 5. Convertible ground cover and backpack 5 may be configured to be used as a ground cover 15A (see, e.g., FIGS. 1 and 2) or, as described herein, converted into a backpack 15B (see, e.g., FIG. 3). One or more embodiments of a convertible ground cover and backpack 5 comprises a tarpaulin 10 (also called “tarp 10”). FIG. 1 illustrates a top-down view of the first side 16 of tarp 10. FIG. 2 illustrates a top-down view of the second side 17 of tarp 10. FIG. 3 illustrates a view of backpack 15B from the side worn next to a user's back. The tarp 10 may be configured in a variety of shapes and sizes, including but not limited to a square or rectangular tarp 10. In implementations where tarp 10 is rectangular (and not a square rectangle), tarp 10 will have two short edges, edges 11 and 13, and two long edges, edges 12 and 14. Tarp 10 is folded along one or more fold lines (e.g., fold lines 50, 51, and 53) so that tarp 10 may convert from operating as a ground cover 15A to a backpack 15B having at least one pocket 95. Tarp 10 may include one or more connecting elements (e.g., waist belt straps 60) configured to couple with a waist belt 70 intended to be clasped around the user's waist during operation as backpack 15B. In operation as backpack 15B, one or two shoulder straps 90 are coupled to tarp 10 by coupling fasteners (e.g., carabiner 75) to grommets 20 and shoulder strap(s) 90.

Referring now to FIGS. 1-6, FIG. 4 provides a more detailed view of FIG. 1, FIG. 6 provides a more detailed view of FIG. 2, and FIG. 5 depicts a call-out view of some implementations of constructing a grommet 20 to couple with tarp 10. In one, non-limiting embodiment, the tarp 10 comprises a 68″ by 58″ inch heavy gauge tear resistant nylon. In some embodiments, tarp 10 has an area of about 10 to 150 square feet, 8 to 70 square feet, 15 to 45 square feet, or 24 to 30 square feet. For example, embodiments having a rectangular shaped tarp 10 may have a variety of rectangular dimensions, including but not limited to: 60″ by 60″, 60″ by 72″, 44″ by 62″, 80″ by 50″, 144″ by 84″, 70″ by 36″, 60″ by 96″, or 60″ by 84″. Any reference to particular dimensions of the tarp 10 or other aspects of a convertible ground cover and backpack 5 disclosed herein are by way of example only and not limitation. For example, convertible ground cover and backpack 5 in some embodiments tarp 10 may have a shape that is circular, elliptical, oblong, irregular, or a polygon having any number of sides capable of being manufactured (e.g., 3-15 sides or even more sides).

The material of the tarp 10 may comprise any suitable material known in the art, such as but not limited to polyethylene, polyester, canvas (such as cotton), or nylon. Water proofing or other coatings may be applied to the tarp 10, such as but not limited to a urethane coating, an ultraviolet light coating (“UVC”), and the like. More particular exemplary materials for tarp 10 may include but are not limited to 70 denier canvas; ripstop 200 denier canvas; 400 denier canvas; 500 denier canvas; 300/600 denier canvas; 600 denier canvas; 1000 denier canvas; and 200 ploy. In one non-limiting embodiment, the material for tarp 10 is 400 nylon and 300/600 poly. In another embodiment, the material for tarp 10 is 600 poly and 1000 nylon. Any reference to particular materials of the tarp 10 or other aspects of a convertible ground cover and backpack 5 disclosed herein are by way of example only and not limitation.

Tarp 10 has a first or inner side 16 according to the non-limiting embodiments of a convertible ground cover and backpack 5 shown in FIGS. 1-6. According to some aspects, tarp 10 comprises an edge 11, an edge 12, an edge 13, and an edge 14. Some embodiments may employ a tarp 10 having a (non-square) rectangular shape where two edges are longer than the other two edges, such as edges 12 and 14 being longer than edges 11 and 13 (see, FIGS. 1-2), or vice versa.

A convertible ground cover and backpack 5 typically further comprises a plurality of grommets 20 coupled to tarp 10, such as where each grommet 20 has a hole extending through tarp 10 and the axis of grommet 20. The plurality of grommets 20 may comprise any material known in the art, such as but not limited to metals, plastics, rubbers, and the like. Grommets 20 may be grommets, washers, teeth washers, neck washers, eyelets, and other reinforcing elements having a void near a central axis. Grommets 20 typically have a circular or ring shaped void (when viewed top-down), but the void may also be one of many polygons (e.g., square, hexagon, etc.) or have an oblong or irregular shape. In the non-limiting embodiment depicted in FIGS. 1-6, the grommets 20 comprise metal grommets. According to some aspects, each grommet 20 may extend not only through the tarp 10, but also through a support material 35 coupled to the tarp 10 adjacent the respective grommet 20. The support material 35 may comprise any material known in the art, such as but not limited to canvas, plastic, rubber, and the like. In some embodiments, support material 35 has a thickness greater than the thickness of tarp 10 and/or has a tensile strength greater than a corresponding area of tarp 10. In certain embodiments, support material 35 may be flexible or rigid and is primarily constructed of one or more of the following materials: rubber, polymer fabric, nylon, natural or synthetic leather, carbon fiber, metal, canvas, plastic, any material disclosed for possible use in tarp 10, and so on. Support material 35 may couple to tarp 10 in various ways, including but not limited to: adhesives, stitching, bonding agents, crimping, welding, soldering, brazing, taping, gluing, cementing, magnets, heat bonding, lashings, grommets, fasteners, ties, clips, staples, and so forth.

In certain embodiments, convertible ground cover and backpack 5 is configured with one or more fold lines to assist the user in properly folding tarp 10 to convert from ground cover 15A mode to backpack 15B mode. For example, tarp may include fold lines 50, 51, and 53, and may allow tarp 10 to be folded into six sections. Those skilled in the art can recognize that tarp 10 may be configured to fold in more or fewer sections with more or fewer fold lines. The fold lines may be for reference only and may or may not represent any physical structure. In some embodiments, fold lines (e.g., fold lines 50, 51, and 53) are identified for the user (e.g., printed or stitched lines), contain elements enhancing the flexibility of tarp 10 near the fold lines (e.g., rubber or flexible fabric), or contain elements enhancing the strength of tarp 10 near the fold lines (e.g., fabric, cable, or cord affixed to the fold lines).

To assist with the description of folding methods and the position of certain elements, six different sections (labeled 1A through 6A and 1B through 6B) are identified on tarp 10, as shown in FIGS. 4, 6-12, 14, and 16-17. These labeled sections are for reference and do not represent an element printed or coupled to tarp 10. Additionally, the sections can be labeled differently, more or fewer sections may be used, or the sections may align with fold lines, other elements of tarp 10, or be otherwise positioned. This disclosure will generally refer to these sections, by way of example only, as follows: section 2A, section 4B, section 5A, sections 3B and 6B, sections 4A-6A, sections 2A/2B, and so on.

Referring still to FIGS. 1-6 and in particular to FIGS. 4-6, the plurality of grommets 20 is typically positioned strategically to allow the tarp 10 to be converted from a ground cover 15A to a backpack 15B, and vice versa. According to some aspects, a grommet 20 positioned proximate each corner of the tarp 10, such as grommets 21, 24, 27, and 30 located at corresponding tarp corners 46, 47, 48, and 49. In these and other embodiments, the convertible ground cover and backpack 5 may further comprise one or more grommets 20 positioned proximate edge 14, edge 12, and each of edges 11 and 13, such as depicted by grommets 22, 23, 25, 26, 28, 29, 31, and 32. In some embodiments, grommets 20 are positioned proximate the outside edges of tarp 10, such as being positioned within six inches (or within 2.5, 4, 8, or 12 inches) of one or more of edges 11, 12, 13, or 14. In some embodiments grommets 20 are positioned proximate each other, such as grommets 25-26 and grommets 31-32 (e.g., positioned no more than 2, 3, 5, or 7 inches away from each other). In some embodiments grommets 20 are positioned separate from each other, such as grommets 21, 22, 23, 24, 27, 28, 29, and 30. In certain embodiments the axis of all grommets 20 coupled to tarp 10 are positioned approximately 0.5-5 inches, 1-4 inches, 2-3 inches, or 2.5 inches away from edges 11, 12, 13, and 14.

FIG. 5 depicts an exploded call-out view of FIG. 4 showing various aspects of the construction of grommets 20 according to some embodiments. Specifically, grommet 30 is shown for illustrative purposes, and primarily comprises a first part 18 and a second part 19. First part 18 may fixedly couple or attach to second part 19 through pressure or another coupling mechanism. In this example, first part 18 and second part 19 are constructed from sheet metal such as aluminum, steel or brass. Support material 35, or support material 44 in this example, is coupled to tarp 10 as depicted by the arrows, and surrounds grommet 20/30 so that at least a portion of support material 35/44 extends beyond the edge of grommet 20/30 (e.g., extending at least 1 cm, 3 cm, 5 cm, or further beyond). As grommet 20/30 intersects support material 35/44, the pressure from grommet 20/30 may assist in coupling support material 35/44 to tarp 10.

Referring now primarily to FIG. 6, one or more embodiments of a convertible ground cover and backpack 5 comprise one or more restraints or coupling straps, such as restraints 65, positioned to couple or capture folded corners of the tarp 10 when the tarp 10 is folded to convert from a ground cover 15A to a backpack 15B. The restraints 65 may be coupled to the tarp 10 with stitching, adhesives, and the like. According to some aspects, the two terminating ends of the restraints 65 are coupled to the tarp 10 such that an opening is formed between the restraint 65 and the tarp 10 between the two terminating ends of the restraint 65. For example, the two terminating ends of restraints 65 may be stitched or otherwise adhered to or coupled with tarp 10. While restraints 65 are utilized in the embodiment shown in FIG. 6, it is also contemplated that other couplings may be utilized, such as but not limited to additional grommets and carabiners, snap buttons, magnets, and the like.

Positioning of the restraints 65 may vary according to the particular implementation of the convertible ground cover and backpack 5. For reference, fold line 50 is positioned approximately central between, and approximately parallel to, edge 12 and edge 14. The fold line 50 extends between, and runs approximately orthogonal to, edges 11 and 13. According to some aspects, edge 12 is a top edge, edge 14 is a bottom edge, and edges 11 and 13 are side edges. Always by way of reference, fold line 51 and fold line 53 extend between, and runs approximately orthogonal to, edges 12 and 14. Fold line 51 and fold line 53 are positioned between, and approximately parallel to, edges 11 and 13. Fold line 51 and fold line 53 may be spaced at approximately equal distances from each other and their nearest side edge 11 or 13.

According to some aspects, a restraint 67 is positioned proximate an intersection of fold line 50 and fold line 53 and primarily within section 6A. More particularly, the restraint 67 is positioned to extend from approximately the fold line 50 to approximately the fold line 53, being primarily or entirely within section 6A.

According to some aspects, restraint 66 is positioned proximate an intersection of the fold line 50 and a fold line 51 of the two lateral lines and primarily within section 2A. More particularly, the restraint 66 is positioned to extend from approximately the fold line 50 to approximately the fold line 51, being primarily or entirely within section 2A.

One or more embodiments of a convertible ground cover and backpack 5 further comprise one or more coupling straps or connecting elements employed as waist belt straps 60. The waist belt straps 60 are typically coupled to the second side 17 of the tarp 10 such that a waist belt 70 may loop through the waist belt straps 60. Coupling of the waist belt straps 60 may be through stitching, adhesives, snap buttons, and the like.

The one or more waist belt straps 60 are typically positioned entirely or substantially within section 5A on second side 17 of the tarp 10 (between edge 12, fold line 50, fold line 53, and fold line 51). More particularly, the one or more waist belt straps 60 may be positioned as just described and proximate fold line 50. In the non-limiting embodiment shown in FIG. 6, the convertible ground cover and backpack 5 comprises three waist belt straps 60, or specifically: waist belt strap 61, waist belt strap 62, and waist belt strap 63. In other embodiments, a convertible ground cover and backpack 5 may comprise any number of waist belt straps 60.

Also contemplated in this disclosure is a method of converting a ground cover 15A according to the above described embodiments to a backpack 15B. According to one aspect, a tarp 10 of a convertible ground cover and backpack 5 is spread out with the first or inner side 16 face down and the second or outer side 17 face up (as shown in FIGS. 2 and 6). The tarp 10 of the convertible ground cover and backpack 5 is folded underneath along the fold line 50 to a first folded position 100 wherein edge 12 and edge 14 are substantially adjacent one another, thereby bringing sections 1B-3B substantially adjacent sections 4B-6B. FIG. 7 depicts the tarp 10 in the first folded position 100. In the first folded position 100, the restraint 66 is typically face up. Furthermore, a first center corner 58 and a second center corner 59 are formed.

Folding tarp 10 into first folded position 100 shown in FIG. 7 may also be achieved where tarp 10 is spread out with the second or outer side 17 face down and the first or inner side 16 face up. Tarp 10 is then folded over along the fold line 50 to a first folded position 100 wherein edge 12 and edge 14 are substantially adjacent one another, thereby bringing sections 1B-3B substantially adjacent sections 4B-6B. Tarp 10 may be oriented such that restraint 66 is face up as shown in FIG. 7.

In one or more embodiments, a convertible ground cover and backpack 5 comprises grommets 31 and 32 proximate edge 11 and grommets 25 and 26 proximate edge 13. More particularly, the grommets 31 and 32 proximate edge 11 may be positioned proximate a center point between tarp corner 46 and tarp corner 49. Similarly, grommets 25 and 26 proximate edge 13 may be positioned proximate a center point between tarp corner 47 and tarp corner 48. Even more particularly, each pair of grommets 31/31 and grommets 25/26 may be positioned so that they are approximately coaxially aligned when tarp 10 is folded into the first folded position 100. Thus, grommet 32 is on top of grommet 31 and an appropriately sized object can pass through the voids of both grommets. Similarly, grommet 25 is on top of grommet 26 and an appropriately sized object can pass through the voids of both grommets.

In one or more embodiments, a convertible ground cover and backpack 5 comprises top edge 12 grommets 28 and 29. Grommets 28 and 29 are typically positioned approximately equal distance from each other and the nearest corner grommets (grommet 27 or 30) of the tarp 10. That is, a grommet 28 is typically positioned approximately ⅓ the distance between grommet 27 and grommet 30, and grommet 29 is typically positioned approximately ⅔ the distance between grommet 27 and grommet 30. In other embodiments, grommets 28 and 29 may be positioned elsewhere along the top edge 12 of the tarp 10 without departing from the scope of this disclosure. Typically, grommets 28 and 29 are equal distance from the nearest corner grommet (grommet 27 or 30).

Similarly, in one or more embodiments, a convertible ground cover and backpack 5 comprises bottom edge 14 grommets 23 and 22. Grommets 23 and 22 are typically positioned approximately equal distance from each other and the nearest corner grommets (grommet 24 and 21) of the tarp 10. That is, grommet 23 is typically positioned approximately ⅓ the distance between grommet 24 and grommet 21, and grommet 22 is typically positioned approximately ⅔ the distance between grommet 24 and grommet 21. In other embodiments, grommets 23 and 22 may be positioned elsewhere along the bottom edge 14 of the tarp 10 without departing from the scope of this disclosure. Typically, grommets 23 and 22 are equal distance from the nearest corner grommet (grommet 24 or 21). More particularly, grommets 28 and 23 and grommets 29 and 22 are typically aligned approximately coaxially with one another such that they are all equal distance from the nearest corner grommet.

FIGS. 8A and 8B depict folding the tarp 10 in the second folded position 102. A method for converting a ground cover 15A to a backpack 15B further comprises folding (see second fold arrow 55) the tarp 10 along the fold line 53 to a second folded position 102 wherein edge 13 is adjacent fold line 51 and section 3A is approximately adjacent and mostly covering section 2A. FIG. 8B depicts the tarp 10 resting in the second folded position 102.

Once in the second folded position 102, a method for converting a ground cover 15A to a backpack 15B further comprises coupling the first center corner 58 to the restraint 66. Coupling of the first center corner 58 to the restraint 66 may comprise inserting the first center corner 58 into the opening of the restraint 66 between the coupling strap and the tarp 10.

Referring to FIG. 9, according to some aspects, coupling the first center corner 58 to the restraint 66 further comprises coupling grommets 25 and 26 proximate the first center corner 58 to the restraint 66 with a fastener, such as a first carabiner 76. FIG. 9 depicts a close up view of a first carabiner 76 coupling grommets 25 and 26 of the first center corner 58 to the restraint 66.
